Filter medium and production method thereof |
摘要 |
A filter medium has a function member accommodated between two fiber layers. A production method for manufacturing a filter medium includes the steps of: preparing a first fiber layer having a shape identical to that of a side surface of the filter medium; disposing a function member on a surface of the first fiber layer; and forming a second fiber layer by spinning partially melted fibers onto the function member disposed on the surface of the first fiber layer. Therefore, it is unnecessary to carry out press-forming in a state in which the function member is sandwiched between nonwoven fabrics, and a countermeasure to prevent the function member from falling out and a countermeasure to prevent the nonwoven fabric from being torn by the function member are unnecessary.
